Commercial air conditioning in Mark Cross, done properly
Once a system is in, it needs looking after. A maintenance contract keeps servicing and leak checks on schedule, with the records kept up to date, at a price fixed with your quote. Our 24/7 emergency line is there if something goes wrong. The work covers VRF systems, ceiling cassettes and server and comms room cooling, and common reasons people get in touch are server rooms running too warm and systems that need out-of-hours or phased installation.
If you run a village hall or similar building near Mark Cross, heating and cooling that warms up fast suits a space used on and off, and it can heat as well as cool.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

What you can do yourself, and what needs us
On air conditioning, the filters in the indoor unit are typically the one part owners can clean, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.

Your questions about commercial air conditioning in Mark Cross
Is Mark Cross in your area for commercial air conditioning?
Yes. Mark Cross is one of the places we cover. Tell us a little about the job and we’ll take it from there.
Is Mark Cross within the area you cover?
Yes, and the size of the place makes no difference to how we work. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Why use an F-Gas certified company?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. In Great Britain, that certification is a legal requirement, not an optional extra, and AirCon Doctor is certified.
What does the operator have to do under the F-gas rules?
Operators of systems from 5 tCO2e upwards need leak checks and records. Checks are at least every 12 months from 5 to under 50 tCO2e, and every 6 months from 50 to under 500 tCO2e and we carry out the checks and keep the records.
What warranty do I get?
Warranty is the manufacturer’s own, on its terms. Terms differ by brand, and we set them out on your quote.
How quickly will you reply?
You will hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
